Amritsar Massacre — British Troops Fire on Indian Crowd

British Brigadier Reginald Dyer ordered troops to fire on an unarmed crowd of thousands gathered in the enclosed Jallianwala Bagh garden for a peaceful protest, killing at least 379 people and wounding over 1,200. The crowd had no way to escape.

The Amritsar Massacre destroyed British moral authority in India and transformed Gandhi's Indian National Congress from a moderate petitioner into a mass independence movement.

Lebanese Civil War1975

Bus Massacre / Black Saturday

On April 13, 1975, Phalangist gunmen ambushed a bus carrying Palestinian and Lebanese passengers through the Beirut suburb of Ain el-Rummaneh, killing 27 people. The attack was retaliation for an earlier shooting that wounded Pierre Gemayel, founder of the Phalange party. Within hours, Black Saturday saw dozens more die in tit-for-tat sectarian killings across the capital.

Widely regarded as the spark that ignited the Lebanese Civil War, the bus massacre transformed simmering tensions between Phalangists and the Palestinian Liberation Organization into open urban warfare that would consume Lebanon for fifteen years.
